What do the election results tell us?
In the US midterm elections on 3 November, Democrats won majorities in both the House of Representatives and the Senate. They made significant gains in states such as Texas, which Republicans had controlled for decades. Democratic socialists expanded their representation in Congress, while local movements challenging large corporations' use of energy and water resources also secured electoral victories across the country.
Opposition to the Trump administration, the cost of living, inflation, the war in Iran and economic insecurity all played a decisive role in the results. Democrats captured at least seven Republican Senate seats and more than two dozen House districts.
Climate change was not a leading issue in these elections. But viewed through energy prices, the fossil fuel industry, corporate power and economic inequality, the results reveal some striking developments.
Three areas deserve particular attention: the growing weight of democratic socialists in federal politics, the political shift in Texas—the heart of the oil economy—and local struggles over the use of energy and water resources.
Democratic socialists gain ground in Congress
Five new candidates backed by the Democratic Socialists of America (DSA) were elected to the House of Representatives:
- Claire Valdez – New York, 7th District. A democratic socialist with a background in the labour movement. Her campaign focused on the Green New Deal, intervention in electricity pricing, public energy investment and workers’ rights.
- Darializa Avila Chevalier – New York, 13th District. She won the Democratic primary against Adriano Espaillat, an influential member of Congress. Her campaign centred on economic inequality, housing and corporate political influence.
- Melat Kiros – Colorado, 1st District. She defeated Diana DeGette, who had represented the district in Congress for 15 terms, in the Democratic primary. The result was also notable for what it revealed about established power within the Democratic Party.
- Donavan McKinney – Michigan, 13th District. Elected from Detroit, he had defeated incumbent Representative Shri Thanedar in the Democratic primary. Union rights, public services and economic inequality feature prominently in his programme.
- Chris Rabb – Pennsylvania, 3rd District. He moved from the state legislature to Congress. His work has addressed labour rights, environmental justice and limiting corporate political power.
Together with Alexandria Ocasio-Cortez and Rashida Tlaib, this brings the number of DSA members in the House to at least seven.
What matters as much as the number is that several of these candidates defeated powerful, established Democratic incumbents in the primaries. The ideological struggle that has been unfolding within the Democratic Party for years now has a more visible presence in Congress.
The Senate race in Michigan also deserves attention in this context.
After defeating Haley Stevens, the more centrist candidate favoured by the Democratic Party establishment, in the primary, Abdul El-Sayed Abdul El-Sayed went on to defeat Republican Mike Rogers in the Senate race. El-Sayed does not describe himself as a democratic socialist. He did, however, receive support from Bernie Sanders and Alexandria Ocasio-Cortez, and campaigned on taxing billionaires, universal healthcare, reducing corporate political influence and tighter regulation of the artificial intelligence industry.
El-Sayed's victory in a competitive state such as Michigan offers an example of left-wing economic policies gaining support beyond the large urban districts where Democrats have traditionally been strongest.
What does this have to do with climate?
In democratic socialist programmes, climate policy, economic inequality and public services are part of the same debate.
Claire Valdez, for example, has published a wide-ranging climate programme. Within the framework of the Green New Deal, she calls for large-scale public investment, a transition to clean energy, union jobs and the development of climate-resilient infrastructure.
Her proposals also include freezing electricity bills, establishing a federal public power authority, supporting states and cities in creating publicly owned energy utilities, and tightening oversight of private energy companies.
To understand the significance of these demands, consider how the current renewable energy transition is unfolding.
Investment in wind and solar power is growing in the United States, but much of the energy market remains under private control. The expansion of renewables does not, by itself, alter a market structure built around the profitability of energy companies. Electricity prices, the costs of infrastructure investment and the distribution of revenue from energy generation remain areas of political and economic conflict.
This is where democratic socialist programmes diverge. They put greater emphasis on public ownership in the energy sector, democratic oversight and public intervention in pricing.
Climate policy thus becomes a debate about how energy infrastructure is run and who benefits economically from it, as well as which technologies generate electricity.
There are substantial political and economic differences between a green transition driven by private investment and one based on public ownership and democratic planning. The growing prominence of this debate on the American left is worth watching.
Texas: Political change at the heart of the oil economy
One of the most striking election results came from Texas.
James Talarico was elected to the US Senate, while Gina Hinojosa defeated Republican Greg Abbott to become the state's first Latina governor. Democrats also won major offices, including lieutenant governor and attorney general.
These developments in Texas carry particular weight for US energy politics.
Texas is the largest oil- and natural-gas-producing state in the country. The Permian Basin is among the world's largest oil-producing regions. The state also has a major petrochemical industry, extensive natural gas infrastructure and a rapidly growing renewable energy sector.
More recently, AI data centres and the enormous investments in energy infrastructure they require have joined this picture.
Political change in Texas therefore bears directly on the balance of power at the centre of the US fossil fuel economy.
Gina Hinojosa: Data centres and corporate privileges
Data centres were one of the prominent issues in new governor Gina Hinojosa's campaign.
Hinojosa called for a moratorium on new data centre construction, an end to the tax privileges granted to companies, and stricter rules on water and electricity use.
The expansion of data centres in Texas has generated serious opposition, particularly in rural communities.
The electricity these facilities consume, the water needed for cooling, the cost of new energy infrastructure and the pressure on farmland are central to local disputes.
According to an ABC News/Washington Post/Ipsos poll published in October, 69% of Texans opposed the construction of new data centres in their own communities.
Opposition is not confined to Democratic voters. Landowners and local communities are also organising against new projects in Republican-leaning rural areas.
Hinojosa's campaign turned that discontent into a political issue.
Technology and energy companies expect considerable returns from investment in artificial intelligence, while local residents are asking what it will mean for electricity bills, water consumption and infrastructure costs.
The conflict of economic interests here is very concrete. In particular, there is the question of whether the costs of new power infrastructure will fall on households or on the large companies consuming the electricity.
The dispute over data centres also raises a question the climate movement is likely to face increasingly often: Who decides which resources technological expansion will depend on, and how its costs will be shared?
James Talarico: Climate policy and the interests of the oil industry
The energy policies of James Talarico, the newly elected senator, tell a different story.
Talarico previously introduced a bill called the Texas Climate Action Act, which proposed targets for reducing the state's greenhouse gas emissions.
During his Senate campaign, however, he adopted an approach that combined protecting jobs in the oil and gas industry with expanding renewable energy investment.
He supports developing wind, solar, geothermal and hydrogen technologies, and explicitly backs the protection of jobs in oil and natural gas.
This reflects the energy policy of a significant part of the Democratic Party: continuing fossil fuel production while expanding investment in renewables.
Texas's economic structure is central to this choice. Oil and gas have an enormous influence on the state's employment, public revenues and political economy.
The tension between the climate movement's demand for a phase-out of fossil fuels and the economic interests of the oil and gas industry is clear here.
Talarico's programme also calls for large data centres to pay for the power infrastructure they need, energy assistance for low-income households, oversight of energy companies' pricing during disasters and stronger environmental regulation.
These are concrete proposals for tighter regulation of the existing energy system.
Jon Rosenthal: A change in the agency regulating oil and gas
Another result of significance for climate and environmental policy in Texas was Jon Rosenthal's election to the Railroad Commission.
Despite its name, this body is primarily responsible for regulating the state's oil and gas industry, rather than railways.
Rosenthal became the first Democrat elected to the commission since 1990.
His campaign focused on stricter oversight of polluting oil and gas facilities, the safety of natural gas infrastructure, fees on the underground injection of wastewater from production, and greater transparency over abandoned oil wells.
These issues go to the heart of the commission's responsibilities. Managing wastewater from oil and gas production, addressing abandoned wells and enforcing environmental standards are directly linked to the long-term public costs of the fossil fuel industry.
Rosenthal's election brings a different political approach into the regulation of the oil and gas industry.
One of the central conflicts in Texas's energy economy lies here: companies retain much of the economic return from production, while the costs of pollution, abandoned facilities, damaged water resources and environmental risks frequently fall on the public.
Corpus Christi: Water rights and a local challenge to petrochemicals
A less widely reported result in Texas came from a ballot measure in Corpus Christi.
Corpus Christi is a major industrial and petrochemical centre where large companies including ExxonMobil, Valero and Occidental Chemical operate.
Prolonged drought in the region has fuelled a serious debate over the water consumed by major industrial facilities and the needs of local residents.
Under the existing system, some large industrial water users could pay a set fee throughout the year to secure exemptions from additional drought-related water rates and certain restrictions.
Local organisations collected around 13,000 signatures to change this arrangement and put the Fair Water Amendment to a public vote.
The measure, also supported by the DSA, passed with roughly 68% of the vote in the 3 November referendum.
It provides for ending the existing exemption programme and imposing mandatory additional charges on large industrial water users at specified stages of drought.
This struggle offers a particularly concrete example of climate justice.
How water consumption is restricted during drought, which privileges large companies receive, and how the economic costs of water scarcity are distributed are all political decisions.
Rather than leaving those decisions to negotiations between large industrial firms and the municipal administration, the movement in Corpus Christi brought them to a public vote.
For petrochemical companies, water is an essential input to production. For local residents, it is indispensable to life and public services.
As the climate crisis brings more frequent and severe water scarcity, conflicts of this kind will become increasingly important.
The method of organising matters, too. Local mobilisation, a petition campaign, political pressure at municipal level and a public vote made it possible to change the rules governing major companies' use of resources.
AI and data centres: A new environmental and economic conflict
Opposition to data centres extends well beyond Texas.
During the 2026 elections, voters in ten states faced 41 local ballot measures concerning the construction, operation or zoning of data centres.
Early results indicated that measures restricting or blocking new data centres had passed in roughly two dozen of those votes.
The measures included construction bans, temporary moratoriums, limits on energy use, requirements for local approval and zoning decisions.
Examples from Ohio, Illinois and other states show that opposition to data centres can bring together voters with different political affiliations.
Behind this development lies the AI industry's enormous demand for energy and infrastructure.
The expansion of AI companies requires more electricity generation and transmission capacity, cooling systems, additional water resources and, in some cases, new natural gas generation capacity.
For technology companies, these are the infrastructure requirements of continued investment. For local communities, they can affect electricity bills, farmland, water resources and the places where people live.
Clean energy investments by the technology sector do not settle these disputes. What new generation capacity is used for, which companies receive public incentives and how the cost of energy infrastructure is distributed remain contested questions.
In recent years, investment in artificial intelligence has largely been discussed in terms of technological progress and economic growth. The election results show an increasingly visible political debate over the social costs of that growth.
The impact of major technology companies on energy and water resources could become an important arena of conflict in US environmental and climate politics in the years ahead.
The political economy of climate policy: Who controls energy?
One issue running through these results is economic power over energy and natural resources.
In recent years, much of climate policy has focused on developing renewable technologies, incentivising private investment and expanding low-carbon production.
These policies have played an important role in the energy transition. Yet the economic and institutional structure of the emerging energy system continues to be shaped largely by existing companies, investors and market mechanisms.
The programmes of democratic socialists and the demands of local movements call for more direct intervention in that structure.
Claire Valdez's proposal for a public power authority, the initiative on industrial water use in Corpus Christi and local campaigns against data centres operate in different arenas. All, however, touch on the relationship between private investment and the management of public resources.
Ownership of energy production and infrastructure, electricity pricing, the allocation of water resources, public incentives for companies and the distribution of environmental costs are becoming more openly political questions.
There is also a clear class dimension to these disputes.
Households paying energy bills, large industrial electricity consumers, workers in the fossil fuel sector, rural communities and energy companies do not always have aligned interests.
There is, for example, a substantial difference between making workers and producing regions bear the costs of a fossil fuel phase-out and carrying out that transition through public investment and job guarantees.
Similarly, renewable energy infrastructure run by private companies can produce different economic outcomes from infrastructure held in public ownership and managed under democratic oversight.
This is why the renewed debate over energy democracy on the American left matters. Addressing climate change is becoming part of a wider economic debate about how production and consumption are organised.
How could the congressional majorities affect climate policy?
Democratic majorities in both chambers of Congress will bring significant changes to the oversight of the Trump administration's climate and environmental policies.
The new Congress will be able to scrutinise federal agencies' spending and regulatory decisions, launch investigations, exert influence over budget processes and use the Senate's power over appointments.
These powers matter particularly for federal environmental agencies, clean energy incentives, permitting for fossil fuel projects and enforcement of environmental law.
Political differences within the Democratic Party will also become more visible.
On one side are Democrats who favour protecting fossil fuel employment and production while increasing investment in renewables. On the other are socialists advocating public ownership, a more far-reaching energy transition and direct measures to limit corporate economic power.
Debates over energy investment, the federal budget, environmental standards and incentives for large companies will bring these differences into focus.
How democratic socialists organise in the new Congress, and how much influence they can exert on the party leadership, will therefore matter.
What do these results tell us ahead of COP31?
With COP31 about to begin in Antalya, these results from the United States reveal important developments in the social and economic dimensions of climate politics.
Global climate negotiations revolve around emissions reduction targets, finance, technology transfer and international obligations.
Questions such as who owns energy infrastructure, the power large corporations hold over public resources, how energy prices are set and how the costs of the transition are distributed across society receive far less attention in international negotiations.
Yet these decisions have major consequences for the implementation of climate policies.
In the US elections, particularly in the programmes of democratic socialists and in local grassroots movements, we can see these economic relationships becoming direct subjects of political debate.
Who controls the energy transition, where public investment goes, what future awaits fossil fuel workers and how essential resources such as water are shared are becoming increasingly visible political issues.
There is also a question here for the climate movement to consider.
Public support for action on climate change depends on more than acceptance of scientific findings or emissions targets. Energy prices, working conditions, housing, transport and basic public services also shape people's views of the transition.
By treating these issues as part of a shared economic agenda, democratic socialist programmes give greater political weight to the relationship between climate policy and everyday life.
Local movements, meanwhile, are taking up these questions through direct struggles over corporate activities, the use of public resources and municipal decisions.
Conclusion: A new climate politics?
Of course, none of this means that climate policy in the United States is now on a secure course.
Despite Democratic majorities in Congress, Trump retains the powers of the presidency and the veto. Serious divisions remain within the Democratic Party over the phase-out of fossil fuels. Democratic socialists still hold a limited number of seats. And Texas's economic dependence on oil and gas will not disappear because of an election.
Nor should the results be treated as a direct vote of support for climate policy. Many voters were motivated by economic conditions and opposition to the Trump administration.
Still, the elections point to a development worth examining.
Demands for intervention in energy pricing, publicly owned utilities, restrictions on industrial water use, local oversight of data centres and limits on corporate political influence are gaining visibility.
They suggest that climate policy may increasingly be debated in terms of economic power and the distribution of resources.
The gains made by democratic socialists expand the representation of these issues in Congress, while local campaigns in Texas and elsewhere have secured concrete regulatory changes at the ballot box.
The coming period will show how far these developments can influence fossil fuel production, energy ownership and public policy.
But a question already deserves the climate movement's attention: As decarbonisation proceeds, will economic power and control over resources in the energy system change as well? Or will the same economic relationships continue through new technologies and investments?
The US midterms show that this question is finding an increasingly visible place in politics.
